Icomoon show up weird after 9 fonts? [migrated]

Icomoon show up weird after 9 fonts? [migrated]

I'm using Icomoon for my site. It shows up correctly for the first 9 fonts.
Here's my code (CSS):
@font-face {
    font-family: 'icomoon';
    src:url('font/icomoon.eot');
    src:url('font/icomoon.eot?#iefix') format('embedded-opentype'),
        url('font/icomoon.woff') format('woff'),
        url('font/icomoon.ttf') format('truetype'),
        url('font/icomoon.svg#icomoon') format('svg');
    font-weight: normal;
    font-style: normal;
}
[data-icon]:before {
    font-family: 'icomoon';
    content: attr(data-icon);
    speak: none;
}
Here's my code (HTML):
<span aria-hidden="true" data-icon="&#xe000;"></span>
<span aria-hidden="true" data-icon="&#xe001;"></span>
<span aria-hidden="true" data-icon="&#xe002;"></span>
<span aria-hidden="true" data-icon="&#xe003;"></span>
<span aria-hidden="true" data-icon="&#xe004;"></span>
<span aria-hidden="true" data-icon="&#xe005;"></span>
<span aria-hidden="true" data-icon="&#xe006;"></span>
<span aria-hidden="true" data-icon="&#xe007;"></span>
<span aria-hidden="true" data-icon="&#xe008;"></span>
<span aria-hidden="true" data-icon="&#xe009;"></span>
All code above works well except these:
<span aria-hidden="true" data-icon="&#xe00a;"></span>
<span aria-hidden="true" data-icon="&#xe00b;"></span>
<span aria-hidden="true" data-icon="&#xe00c;"></span>
<span aria-hidden="true" data-icon="&#xe00d;"></span>
<span aria-hidden="true" data-icon="&#xe00e;"></span>
I choose it together in a pack from Icomoon, but I think because of the last character that prevent it from showing up. F.e: a, b, c, d and e.
It shows something like cube shape.
Does anyone know how to solve these issue?
Thanks!
